There are three different types of fat cells: white fat cells act as energy storage, brown fat cells produce heat, and beige fat cells can convert to white fat and back to beige or brown fat when stimulated by cold. White fat cells consist of a single large fat-droplet surrounded by a thin layer of cell plasma containing only a few energy-producing mitochondria. Brown fat cells, on the other hand, contain several small fat-droplets and a larger proportion of cell plasma with a much higher number of mitochondria. Beige fat cells are embedded in white adipose tissue and contain both fat-droplets and a relatively large number of mitochondria.
